[Dovecot] SSL hangs? Try this
by Timo Sirainen 09 Aug '06

09 Aug '06

Since apparently 1.0 RC5 didn't fix the SSL hangs for everyone, could you try if replacing src/login-common/ssl-proxy-openssl.c with this helps: http://dovecot.org/tmp/ssl-proxy-openssl.c It's basically the old proxying but with some new changes, plus hopefully also fixing the original rarely occurring hang which my rewrite was intended to fix.

[Dovecot] When auth_process_size is reached
by Bill Boebel 09 Aug '06

09 Aug '06

What does Dovecot do when dovecot-auth reaches the max size defined by auth_process_size? Does it just prevent it from growing further, or does it cause any problems? Thanks, Bill

Any other suggestion ? You can modify the "capability" variable around line 31096 of the "configure" file before you compile dovecot. Bill

[Dovecot] Issue building rc6 on Mac OS X (quota)
by James Berry 09 Aug '06

09 Aug '06

I haven't had time to put together a patch, but quota-fs.c fails to compile on Mac OS X. Any chance we could get a configuration switch that says "--without- quota"? I've resolved the problem temporarily by forcing HAVE_FS_QUOTA to undef in quota-fs.h. James

Re: [Dovecot] Dovecot imap with Postfix and using Thunderbird as client
by Shawn Needham 09 Aug '06

09 Aug '06

Hi, I was wondering if anyone knew of the mysterious fix to this problem that Curtis describes in his followup: "I vaguely remember something like this, but I don't recall the fix" I recently installed dovecot on a server running RHEL4-AS-U2 and have updated to RHEL latest dovecot package, dovecot-0.99.11-2.EL4.1. Seeing as this is close to the version Curtis is running (dovecot-0.99.14) I was wondering if anyone had some insights. There seems to be a Thunderbird specific problem when trying to retrieve messages from the server. Other imap clients (Mac OSX Mail, squirrelmail, etc) don't experience this problem, however Thunderbird 1.5.0.5 experiences it on Linux, Mac OSX and Windows boxes. In thunderbird, new messages don't reliably appear and the retrieval button doesn't work when new mail is present. Clicking on an email which isn't cached retrieves new ones as well as waiting around an hour to retrieve messages. Thanks in advance for any insight you can provide.

[Dovecot] Can't move messages
by Paul van Erk 09 Aug '06

09 Aug '06

Hi, I use dovecot with IMAP over SSL and with Plain Text authentication. I've been using that for quite a while, but now (with my new PC), it's not working like it should (I tried several 1.0* releases, including 1.0-rc6. The problem is that I can't move messages from one IMAP folder to another, no matter which mail client. When I use KMail, I get: "The connection to the server parena was unexpectedly closed or timed out. It will be re-established automatically if possible." But everything still works. The messages hasn't moved (deleting (so send to Trash folder) also doesn't work), it stays where it is. With Thunderbird, it just goes nuts in the status bar saying "Connecting..." and some other messages: clearly it tries to move, loses the connection and tries again and again... An extra weird thing is when I move a message from my IMAP account to a local folder, it works. And then I can move that message from the local folder to my IMAP account. It only doesn't work when moving messages within the IMAP account. I use: openssh 4.3_p2-r1 openssl 0.9.7j I hope someone can help me, 'coz my wife will soon start to find it just as annoying as I already do. ;) Paul van Erk

[Dovecot] rc6 compilation problems (obsd 3.9 stable)
by Michal Soltys 08 Aug '06

08 Aug '06

Starting with rc6, there seem to be problem with compilation on openbsd 3.9, (possibly due to autoconf 2.60 switch mentioned in other thread ?). Either way, this is what configure reports at some point (further compilation fails of course): checking for crypt... yes checking for dlopen... yes checking whether byte ordering is bigendian... no ./configure: echo $(top_builddir)/src/lib-storage/index/maildir/libstorage_maildir.a: not found ./configure: echo $(top_builddir)/src/lib-storage/index/mbox/libstorage_mbox.a: not found ./configure: echo $(top_builddir)/src/lib-storage/index/dbox/libstorage_dbox.a: not found checking zlib.h usability... yes checking zlib.h presence... yes checking for zlib.h... yes

[Dovecot] Dynamic server address
by Kresimir Tonkovic 08 Aug '06

08 Aug '06

Hi! My mail server (ubuntu breezey badger) is connected by ADSL and has a dynamic address. I have noticed that, every day after the IP address changes, dovecot is no longer reachable from the net. Iguess this is because dovecot doesn't register this change and continues to listen on a non-existing interface/address. I'm trying to solve this problem by putting a script in /etc/ppp/ip-up/ dovecot --===--- #!/bin/sh # By kresho # dovecot ip-up script (/etc/ppp/ip-up.d/dovecot) # /etc/init.d/dovecot restart ---===--- So far, it seems to work. I doubt I'm the first one to come across this problem, yet I couldn't find anything similar on google. Any comments? -- kresho

Hi all, Firstly if this is a FAQ and I've missed it - let me apologise in advance. I use dovecot as a backup mail store and would now like to purge all mails over a certain age. Is it as simple as using find and rm'ing the results or is there more to it? I'm using maildir if that make a difference? Thanks in advance. Daveh

[Dovecot] RC6 startup failure: "Login prcess died too early"
by S JList 07 Aug '06

07 Aug '06

Greetings. I have been running Dovecot-1.0rc2 on a test server for the last couple of weeks. No problems. However, when I installed RC6 this morning, Dovecot refused to launch completely. Here's the relevant snippet from /var/log/maillog: Aug 7 10:08:36 mercury dovecot: Dovecot v1.0.rc6 starting up Aug 7 10:08:37 mercury dovecot: Login process died too early - shutting down Aug 7 10:08:37 mercury dovecot: child 26127 (login) killed with signal 11 Aug 7 10:08:37 mercury dovecot: child 26128 (login) killed with signal 11 Both RC2 and RC6 compiled cleanly with "--with-pop3d". For reasons beyond my control, I have to set protocols = imap pop3 disable_plaintext_auth = no ssl_disable = yes I do have a valid /etc/pam.d/dovecot file (we're using PAM). I made certain that the localized settings for /usr/local/etc/dovecot.conf matched what they were in RC2 for RC6. (I did use the RC6 dovecot-example.conf as source for RC6, then made the local changes. I also tried testing RC6 with my old RC2 config file--same failure). So, RC2 starts just fine. RC6 fails to start with the messages logged above. Can anyone give me any pointers? RHEL (Linux Kernel 2.6.9-34.0.2.ELsmp), built from source, nothing out-of-the-ordinary. Right now, I've reverted back to RC2. TIA. S JList sjlist(a)heidelberg.edu

[Dovecot] Stale imap processes
by Martin Jackson 07 Aug '06

07 Aug '06

Hello, I'm new to the list, but I noticed a buildup of stale imap processes after upgrading to 1.0rc2. My IMAP server actually ran over maxpipekva, and I had to reboot it. I got to spend some time learning about kern.ipc.maxpipekva in the process of troubleshooting. I'm running FreeBSD 6.1-RELEASE-p3, and I have a small home office LAN setup. 2 XP client PC's, one which uses primarily Thunderbird 1.5.0.5, one which uses primarily Outlook Express. I had been running with SSL under Thunderbird (only), but disabled that in hopes of fixing the problem. It appears not to have helped. I am using the FreeBSD dovecot port, currently at rc2, with default settings. I use the default authentication scheme, and Maildir storage (my MTA is Postfix). I am running a number of other daemons on this machine but mail is its main function. I am interested in helping to solve this problem; is there anything I can do to help? Thanks, Marty

[Dovecot] 1.0 RC6 released
by Timo Sirainen 07 Aug '06

07 Aug '06

http://dovecot.org/releases/dovecot-1.0.rc6.tar.gz http://dovecot.org/releases/dovecot-1.0.rc6.tar.gz.sig Back to rc1's SSL proxying code with some improvements, which hopefully now makes everyone happy. I'm seeing all kinds of problems with namespace prefixes and LIST code. I guess it would be important to fix it before v1.0 since it makes upgrades from other servers easier.. I also tried looking into the "Unknown namespace" problems that happens if you try to create only one namespace with "INBOX." prefix. I couldn't really figure out what causes those errors. Could someone show me what commands the client tries to use which causes it? * Removed login_max_logging_users setting since it was somewhat weird in how it worked. Added login_max_connections to replace it with login_process_per_connection=no, and with =yes its functionality is now within login_max_processes_count. + Added --with-linux-quota configure option to specify which Linux quota version to use, in case it's not correct in sys/quota.h. Usually used as --with-linux-quota=2 + acl plugins: If .DEFAULT file exists in global ACL root directory, use it as the default ACLs for all mailboxes. - Fixes to login process handling, especially with login_process_per_connection=no. - Back to the original SSL proxy code but with one small fix, which hopefully fixes the occational hangs with it - Several fixes to handling LIST command more correctly.

[Dovecot] Dovecot proxy: Too many open files
by Bill Boebel 06 Aug '06

It appears that when running Dovecot as a proxy-only box with "login_process_per_connection = no", it ignores the value of login_max_logging_users. And in Linux, since each socket requires a file descriptor, if you don't increase the maximum number of open files that each process is allowed to have open, imap-login will reach the 1024 open file limit and start logging the following errors: imap-login: socket() failed: Too many open files imap-login: Internal login failure: user=... imap-login: socketpair() failed: Too many open files Here are the settings I am testing with: login_process_per_connection = no login_max_logging_users = 225 login_processes_count = 20 login_max_processes_count = 30 And here the output of "lsof -nu dovecot" when one of the imap-login processes reaches its open file limit. In this case PID 20087 had 362 users connected, but it should have allowed no more than 225 users, which would have kept it from reaching the open file limit: (sent directly to Timo since it was too big to post to the list) Also, I am running CVS dovecot-20060725.

[Dovecot] Using mail_chroot and default_mail_env
by Daniel Kauffman 06 Aug '06

06 Aug '06

Settings for mail_chroot and default_mail_env are not playing well together. It seems that default_mail_env is verified to exist *before* the chroot but is later used *after* the chroot. A configuration like this: * mail_chroot = /var/mail/example.com/username * default_mail_env = maildir:/Maildir Fails with the message: * stat(/Maildir) failed: No such file or directory As a work-around, I created an empty directory named Maildir *outside* of the chroot. The relevant portions of the filesystem now look something like this: * /Maildir * /var/mail/example.com/username/Maildir/... NOTE: The empty /Maildir directory is owned by root. NOTE: Each /var/mail/example.com/username directory and up is owned by root. NOTE: Each /var/mail/example.com/username/Maildir directory and below is owned by the email user. After successful testing with the "static" settings above, I was able to pull the per-user settings for mail_chroot in from PostgreSQL using home to over-ride mail_chroot. If anyone else has been having trouble with mail_chroot + default_mail_env, hopefully this work-around will help. Finally, I should mention my system, just in case I am the only one affected... * Xen + Linux 2.6.16.13 + Debian 3.1 + ( Dovecot 1.0rc2 in chroot ) Regards, Daniel Kauffman
